In the third part of their discussion, Dave Sloan and Robert Brandenberger explain the relationship between string theory and inflationary models. Can inflation arise from particle physics, or do we need to look for alternative models?

In the second part of their discussion, Dave Sloan and Robert Brandenberger tell us what inflation predicts and whether inflation itself seems fine-tuned. This discussion was conducted at the University of Oxford on March 14, 2017.

In the third part of their discussion, Mario Livio and Joe Silk ask: could our theories exceed our ability to test them? Have they already? This discussion was conducted at Trinity College, Oxford, on February 12, 2016.

Members of the Rudolf Peierls Centre for Theoretical Physics hosted the 3rd morning of Theoretical Physics. The event focused on the interface between theoretical developments in particle physics and astrophysics/cosmology.
